Polhemus Micro Sensor 1.8
The Micro Sensor 1.8 is one of the latest breakthroughs from Polhemus, the leaders in motion measurement innovation. This 6DOF (6 Degree-Of-Freedom) micro sensor tracking element utilizes Polhemus proprietary AC electromagnetic technology, weighs in at less than a gram, and measures only 1.8 millimeters in OD (outer diameter). Small and lightweight, it packs an enormous amount of capability into its small size and provides both position and orientation data, at speeds up to 240 Hz (frames of data per second).
Like all Polhemus tracking technology, the new Micro Sensor 1.8 requires no line-of-sight to continuously track its position and orientation. Better still, Polhemus sensors are completely embeddable into a variety of custom form factors, ideal for fitting inside a traditional catheter, a head-worn device, such as an HMD, simulated medical tools, or even slipped under gloves or clothing. This makes the Micro Sensor 1.8 an ideal tracking solution for applications requiring not only high-fidelity precision tracking, but also small-scale sensor size.
Currently for use with Polhemus LIBERTY™ and PATRIOT™ motion tracking systems, the Micro Sensor 1.8 offers tracking capabilities of up to 16 sensors simultaneously per system. Polhemus AC electromagnetic technology allows for multiple tuned magnetic tracking sources which enables you to run independent tracking systems right beside each other without concern for magnetic overlap (cross talk).

Polhemus technology has been used in the healthcare market for years, including healthcare simulation and real-world applications such as enabling image guided surgery. The Micro Sensor 1.8 adds new capability and value to healthcare and other important markets.
